masc nom sg of upāsaka (noun)
Analysis. upa + āsaka: upa 'up close to, near' + āsaka 'one who sits', from √ās 'to sit'. The concrete image is physical proximity — sitting near the teacher — which comes to mean spiritual allegiance.
Etymology. upa- (approach, nearness; cognate with Sanskrit upa, Greek hypo-, Latin sub-, English up) + √ās 'sit' (Sanskrit āste, cognate with English sit). The word crystallizes the monastic scene: a lay person sitting near the Buddha or a teacher, hence becoming a devoted follower.
